There is strong anecdotal evidence that Enterprise Architecture (EA) brings benefits to organisations and that organisations are investing significantly in EA initiatives. However, demonstrating the business value of EA has proven elusive. Many of the benefits of EA are intangible and value is achieved indirectly within business change projects. Furthermore, it is not the EA itself that provides benefits, it is the ability to provide advisory services enabled by the EA that is important. In this paper we focus on EA service capability and develop and test a new research model that explains how EA service brings benefits to organisations. Our findings highlight the importance of EA service capability and dynamic capabilities in creating benefits from EA.
